As a machinist, he hasn't met a metal he couldn't master. But as a son, Adamcik is terrified his parents will find out about his moonlighting job: Making pretzels out of opponents.

"They still don't know I'm a fighter," says Adamcik, who will fight Saturday in the Legacy Fighting Championship Punishment card at the Pavilion in Stampede Park.

"I don't tell them. I see them often enough, but I just don't talk about it."

Adamacik's parents migrated to Calgary from the Czech Republic when Peter was three. The 29-year-old welterweight isn't convinced they would understand his choice of hobbies.

"They're old school, and they'd say that it's dangerous and a waste of time, that I should be out working and starting a family," he said.

With his parents comfortably in the dark over his part-time job, the Bishop Grandin graduate quietly trains out of the Dragon's Den in Inglewood with the Emergent Fight Team. He splits his training between Muay Thai and Brazilian jiu-jitsu with a heavy dose of conditioning -- especially as fight night nears.

"You have to be able to last the entire fight," he said, punctuating the importance of his cardio training.

Adamcik says his strength is on the ground, specifically submission grappling. He has a 1-2 record with his win coming by way of an armbar.

For his fourth fight, Adamcik will take on Adam Farr.

"I've seen him fight once and I've heard he's a fairly good grappler, which suits me fine. I'm fairly comfortable down there," said Adamcik.

He says he has no plans to pack up his tools at Proficient Machineworks and join the fight game full-time.

"Right now, I'm seeing how much success I can have," he said. "I have a full-time job and a full-time career, and I love fighting and training and teaching."

As for his parents, Adamcik says with the surging popularity of the sport, he'll likely have to cross that bridge sooner rather than later.
